If you trick the ECM into thinking that it is colder outside, it will dump more fuel in the engine. That is what those devices do. They make the engine run very rich. If you can't move more air thru the engine, they are a waste, and you won't see any performance gains.
Well, I've got the 4cyl so I can't use the other "performance chip" on ebay. I'm running a turbocharger and I want a little extra help with fuel. I seem to be running a little lean, and I think this thing could help...
